密码和手势锁屏已经过时何不试试更安全的涂鸦锁屏

　　That locking mechanism on your tablet computer or smartphone? It’s mostly a relic from the days of the keyboard. With the advent of touchscreens, the three-by-three grids and four-digit passcodes popular on today’s mobile devices are anachronistic. Yet they persist, despite “shoulder surfers” and the telltale oilsleft by swiping fingers.

　　眼下平板电脑或智能手机上的锁屏程序可谓键盘时代的遗物。随着触摸屏的出现，如今移动设备上常用的“九宫格”式和四位密码都过时了。然而，它们仍然在广泛使用，尽管老有人站在别人身后偷窥，而用户手指划过屏幕时留下的油迹也会泄露密码。

　　A new study from Rutgers University suggests that squiggling—yes, squiggling—on the screen of your tablet or smartphone may provide a better authentication mechanism than the standard pattern locks favored by Google’s GOOG 1.54% Android operating system and the Personal Identification Numbers (PINs) preferred by Apple’s AAPL -0.09% iOS.

　　美国罗格斯大学(Rutgers University)一项新研究表明，在平板电脑或智能手机上信手涂鸦可能是比谷歌(Google)安卓( Android)操作系统所采用的标准模式锁屏以及苹果(Apple)所青睐的个人识别号码(Personal Identification Numbers, PINs)更好的身份验证机制。

　　“The current locking and authentication mechanisms available for mobile systems commercially do not work so well,” said Janne Lindqvist, an assistant professor of electrical and computer engineering at Rutgers University and an author of the study. “Instead of having old methods or cued methods, we let people just generate gestures without any kind of visual cue or other kind of instructions.”

　　研究报告的执笔人之一、罗格斯大学电气和计算机工程助理教授珍妮o林奎斯特称：“目前移动系统采用的商业化的锁定和身份验证机制不太好用。我们弃用给用户提示的老方法，转而让用户在屏幕上信手涂鸦，不存在任何视觉提示或其他类型的指示。”

　　The studies’ researchers, which included collaborators from the Max-Planck Institute for Informatics and the University of Helsinki, asked 63 participants to scrawl “continuous free-form multitouch gestures,” essentially finger-painting on the blank touchscreen canvas of a Google Nexus 10 tablet. No grid, no template: the subjects improvised a pass-doodle, rather than a password.

　　这项研究的研究人员包括来自马普信息学研究所(the Max-Planck Institute for Informatics)以及赫尔辛基大学(the University of Helsinki)的合作者。他们请63位被试者以“连续不规则多点触控手势”信手涂鸦，本质上是以谷歌Nexus 10平板电脑的空白触摸屏为画布，以手指为笔作画。没有“九宫格”，也没有模版，被试者即兴创作的是“密画”，而非密码。
